Water driven agitator



Jan. 3, 1939. D. CANADY WATER DRIVEN AGITATOR Fild July 19, 1938 INVENTOR. Jazz [222 26 QGMQH A TTORNEYS Patented Jan. 3, 1939 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to an apparatus suitable for agitating a developing solution or reagent used in the photograph art and especially cinematograph film, in an efficacious and automatic manner.

An object of the invention is to provide a simple, efficient and dependable device for the above purpose.

Various other objects and advantages will be apparent as the nature of the invention is more fully described.

The invention and its aims and objects will be readily understood from the following description taken in connection with the accompanying drawing of one embodiment of the invention herein given for illustrative purposes, the true scope of the invention being more particularly pointed out in the appended claim.

Referring to the drawing:

Figure 1 is a longitudinal section of the apparatus taken on line AA in Figure 2. The fluid actuated turbine rotor is not shown in section but in full side view.

Figure 2 is a plan view of the apparatus.

The apparatus consists of a small turbine rotor l in the casing 2, which is freely mounted on the horizontal shaft 3 in the casing 2. The casing is provided with a removable cover 4, and is held in assembled relation with the casing by means of threaded screws 5, 5, 5, 5 and 5. The threaded bores for the reception of the threaded screws are shown at 6, l, 8, 9 and II! in Figure 1.

The casing is provided with a fluid container l I adapted to contain a developing solution or reagent. The container may be conveniently aflixed to, or may be integrally formed with the casing. The container may be provided with a cover or closure rendered liquid-tight in any suitable manner, not shown.

The resilient or flat spring supporting members I2 and I3 may be of interrupted cylindrical configuration, and are bent on the same radius so that they are equally stressed, and are rigidly attached to the casing in any suitable practical manner as at I 4 and IS. The springs or resilient supporting members maintain the fluid container in parallelism with the support on which the apparatus may be set.

The turbine rotor is provided with an arcuate or segmental through opening 16. It will be noted that the rotor as constructed is provided with a heavy side I! opposite the arcuate opening 16.

The water is conveyed to the rotor by means of a suitable conduit or hose I8, attached at one end to a suitable water supply under pressure, (the water supply not shown), and at its other end I9 to the nozzle or orifice 2B. The water under pressure is discharged through the nozzle and impinges upon the vanes 2| of the rotor, thereby imparting rotation to the rotor. The vanes may be milled from the solid rim of the rotor if desired. The water is discharged through the opening 22 in the casing.

The rotation of the rotor in the casing is constrained because of the construction of the rotor proper, due to the resistance caused by the heavy side therein, with the result that there is transmitted to the container through the jointly cooperating spring members an oscillatory motion, which in turn agitates the liquid in the container associated with the casing. Obviously a cam fixed to the turbine rotor shaft, the rotor being fixed to the shaft, may be used to agitate the liquid.

It is believed that the operation of the apparatus as a whole will be clear, in view of the foregoing description which has been given in connection with the construction of the same.

It is to be understood that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes of said invention, and I therefore desire that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claim rather than the foregoing description to indicate the scope of the invention.

What I claim as new and desire to secure by Letters Patent of the United States is:

In an apparatus of the class described comprising a unitary casing having formed therein a liquid containing compartment, and a water driven source of agitation housed in the unitary casing below the liquid containing compartment, rigidly secured fiat leaf springs of duplicate configuration projecting equally and laterally from opposite sides of the casing and being of interrupted. cylindrical formation, the aforesaid flat leaf springs providing resilient supporting members for the unitary casing so that the casing is equally supported upon'both sides of its median line by members that have a tangent with the supporting plane.
